How to solve P = (Q + B)/r

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

Question

$$P=\frac{Q+B}{r}$$

Solve for B

$B=Pr-Q$
$r\neq 0$

Solution Steps

Multiply both sides of the equation by $r$.

$$Pr=Q+B$$

Swap sides so that all variable terms are on the left hand side.

$$Q+B=Pr$$

Subtract $Q$ from both sides.

$$B=Pr-Q$$

Show Solution

Solve for P

$P=\frac{B+Q}{r}$
$r\neq 0$
